Downhole vibratory bypass tool

Abstract

A downhole tool is disclosed herein that has an inlet for receiving fluid into a housing of the downhole tool. The downhole tool further includes a vibratory apparatus at least partially disposed within the housing of the downhole tool, the vibratory apparatus having an operational flow path disposed therein to operate the vibratory apparatus when fluid flowing through the operational flow path is above a predetermined pressure. Furthermore, the downhole tool has a bypass passageway disposed in the housing for providing an additional flow path for fluid through the downhole tool to prevent fluid from reaching the predetermined pressure in the operational flow path of the vibratory apparatus, the bypass passageway selectively blockable such that fluid in the operational flow path is increased above the predetermined pressure to activate the vibratory apparatus when the bypass passageway is blocked. A method of using the downhole tool is also disclosed.

What is claimed is: 
     
       1. A downhole tool, the tool comprising:
 an inlet for receiving fluid into a housing of the downhole tool; 
 a vibratory apparatus at least partially disposed within the housing of the downhole tool, the vibratory apparatus having an operational flow path disposed therein to operate the vibratory apparatus when fluid flowing through the operational flow path is above a predetermined pressure; 
 a bypass passageway disposed in the housing for providing an additional flow path for fluid through the downhole tool to prevent fluid from reaching the predetermined pressure in the operational flow path of the vibratory apparatus, the bypass passageway selectively blockable such that fluid in the operational flow path is increased above the predetermined pressure to activate the vibratory apparatus when the bypass passageway is blocked; and 
 a first screen disposed in the housing uphole of the vibratory apparatus to direct a fluid blocking member toward the bypass passageway and permit fluid to flow to the vibratory apparatus. 
 
     
     
       2. The tool of  claim 1  wherein the downhole tool further includes a second screen to prevent the fluid blocking apparatus from blocking fluid from entering the operational flow path of the vibratory apparatus. 
     
     
       3. The tool of  claim 1  wherein the vibratory apparatus is disposed entirely in the housing of the downhole tool. 
     
     
       4. The tool of  claim 1  wherein the bypass passageway includes a seat for engagement with a fluid blocking member. 
     
     
       5. The tool of  claim 2  wherein the second screen is disposed at an inlet of the operational flow path of the vibratory apparatus. 
     
     
       6. A method, the method comprising the steps of:
 running a bottom hole assembly into a wellbore, the bottom hole assembly includes a downhole tool, the downhole tool comprising:
 an inlet for receiving fluid into a housing of the downhole tool; 
 a vibratory apparatus at least partially disposed within the housing of the downhole tool, the vibratory apparatus having an operational flow path disposed therein to operate the vibratory apparatus when fluid flowing through the operational flow path is above a predetermined pressure; 
 a bypass passageway disposed in the housing for providing an additional flow path for fluid through the downhole tool to prevent fluid from reaching the predetermined pressure in the operational flow path of the vibratory apparatus, the bypass passageway selectively blockable such that fluid in the operational flow path is increased above the predetermined pressure to activate the vibratory apparatus when the bypass passageway is blocked; and 
 a first screen disposed in the housing uphole of the vibratory apparatus to direct a fluid blocking member toward the bypass passageway and permit fluid to flow to the vibratory apparatus; 
 
 flowing fluid into the bottom hole assembly to perform oil and gas operations; 
 initiating a vibratory operation in the wellbore; 
 stopping the vibratory operation in the wellbore; and 
 continuing to perform oil and gas operations. 
 
     
     
       7. The method of  claim 6  further comprising the steps of:
 initiating a second vibratory operation in the wellbore; 
 stopping the second vibratory operation in the wellbore; and 
 continuing to perform oil and gas operations. 
 
     
     
       8. The method of  claim 6  wherein the downhole tool further includes a second screen to prevent the fluid blocking apparatus from blocking fluid from entering the operational flow path of the vibratory apparatus. 
     
     
       9. The method of  claim 6  wherein the vibratory apparatus is disposed entirely in the housing of the downhole tool. 
     
     
       10. The method of  claim 6  wherein the bypass passageway includes a seat for engagement with a fluid blocking member. 
     
     
       11. The method of  claim 6  wherein the second screen is disposed at an inlet of the operational flow path of the vibratory apparatus.
